MDS824
Conventional base mountable sounder
The conventional base mountable sounder (MDS824)
has a slim and aesthetically pleasing design and can
be installed as either a discreet stand alone sounder or
ceiling mounted with a detector and base.
The MDS824 is compatible with the Eaton range of
conventional detectors and fire systems.
Mounting with a detector and base simplifies the
installation of the system by enabling a detector and
sounder to be fixed at a single common point.
When used as a stand alone sounder the device can be
either wall or ceiling mounted and completed with an
optional cover plate (MDS824COV).
These conventional base mountable sounders are
ideal for applications such as hotel bedrooms where a
detector sounder is required.
Features and benefits
• Discreet appearance
• Can be used with a detector as a sounder base or
stand alone as a sounder
• Cover plate (optional)
• Quick and simple to install
• Discreet low profile design
• Single installation point
